Bought two of them today on different channels. My 11 year old has no idea how lucky he is to have a dad like me who is into all of this stuff. Just tested them out today and they are very cool. Bought the infra versions and when they get hit, do they shake. On the sixth hit, the thing goes nuts and then sits and flashes lights till you reset it. Will be a lot of fun stalking each other out all over my place. Can see my 7 year old daughter getting into it too.
